Glossary
ASTM Protocol
A standardized computer interface specification following the guidelines from the American
Society for Testing and Materials.
Autoloader/Offload Track
When viewed from the front of the system, the autoloader is on the left and holds up to 25
sample racks in preparation for presentation to the DxC 800 system. The DxC 600 system has
room to load a maximum of 14 racks.
There is also space for 25 sample racks in the offload track as they are removed from the Sample
Carousel upon completion. Combined, these two components allow for over one hour of
uninterrupted sample processing, with no operator intervention involved.
Auto ORDAC
Automatic Overrange Detection and Correction. A system feature that detects a chemistry
result that exceeds the instrument analytical range.
Back-to-Back
A measure of system precision during calibration. The difference in the response from two,
usable calibrator replicates.
Bar Code Reader (Sample)
The Bar Code Reader is a Class II fixed-beam laser scanner. It is used to read the rack bar code,
the sample bar code (if present), and the background bar codes as the rack travels past. The rack
bar code and sample bar code (if present) are used to identify the sample and link it to the
appropriate sample programming.
Batch
A group of samples with identical sample programming information, with the exception of the
Sample ID.
Baud Rate
The serial data transfer speed between two or more communication devices.
Bidirectional Interface
Two-way transmission of information from the host computer to the instrument (usually
sample programming) and from the instrument to the host computer (usually results).
Blanked
A sample or reagent baseline, photometric measurement subtracted from the reaction read
window measurement.
Calculation, Beckman Coulter-Defined
A calculation formula, supplied by Beckman Coulter, which is uneditable and undeletable.
Cartridge Chemistries (CC)
Chemistries whose reagents are packaged in a three-chamber cartridge designed to hold up to
three levels of reagent.
Check Digit
A character used to mathematically check that a bar code is read accurately.
